You are not screwed. I was in the same boat as you, only my exam results had the additional misfortune of being damaged in a house move by some cooking oil. Oil on that paper makes it translucent and the markings are pretty much gone. I sent them in (finally) with an explanation of the damaged sheets. I could not get a replacement copy from my instructor though.
Miramichi got the letter, processed everything, did the calls and I got my license in the mail with no problems. No problems with being a long term depression sufferer as well. Let the lady doing the interview know how long it had been going on for and she asked if I followed up with a Dr. Told her the truth that I follow up with my Dr every few months and the meds are stable. Not a problem at all.
It isn't at all as bad as some may make it seem to be. Check the web site often, remember that there is like a 28 days waiting period too before they will move on anything. Send it registered, signature required and track it online via Can Post so you know when it arrives and the 28 days starts.
